Product Introduction

 

Yokohama Rubber Fender is constructed of synthetic-cord-reinforced rubber sheets with compressed air inside to keep floating over the water surface and work as a shock absorber between two ships or between ships and berthing structure when they come alongside each other on the water.

Pneumatic Rubber Fender is a leading anti-collision device for marine application in the world today. Pneumatic Fender has become an idea ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbors and wharves.

 

Usually aircraft tires or truck tires are used toprotect the fender body. Both ends are equipped with shoulder straps, which are widely used for ship-to-ship transfer operations and ship berthing operations. Wait. The rubber Yokohama fenders are produced in strict accordance with ISO17357-2014 international quality standards, and the products are exported to all over the world.

 

Pneumatic Rubber Fenders are suitable for many applications including:

1. Tankers, Gas Carries and Bulk Cargo Ships;

 

2. Fast ferries and aluminum hulled vessels;

 

3. Temporary of permanent installations;

 

4. Rapid response and emergency fendering;

 

5. As stand-off fenders to realign ships with shore facilities.

Advantage of Rubber Yokohama Fender

 

Advantages During Inclined Berthing

 

During berthing, the initial contact with the dock is usually at an oblique angle and that places a lot of pressure on both surfaces (the dock and the ship).

For typical solid rubber fenders, at inclined compression which is usually the case, energy absorption decreases considerably. Therefore, it is not unusual to see solid fenders used are larger in sizes. On the other hand, pneumatic fenders’ energy absorption maintains at a relatively high level despite inclined compression. Due to a more evenly distribution of load pressure, the torque performance against the dock is usually smaller when compared to conventionally designed solid fender systems.

 

Stronger Against Shearing Force

 

After making contact with the dock, the vessel is usually slowly moved to the optimum mooring position. This action exerts high shearing force and compression on the surface of fenders. Most solid fenders are severely damaged due to such forces as they are not designed to withstand strong shearing forces and friction that way. However, it depends on the designs/types of solid fenders. For example, MAX frontal pads for solid fenders are designed to tackle this issue and protect the fenders from shearing forces, in which the surface of fenders do not make contact with the ship.

 

Relatively Safe Even During Excess Load

 

Generally speaking, all fenders should be used within the impact load limit. However in real life situations, it is common to see that fenders often accidentally receive excess loads. When that happens, the fortunate thing about a pneumatic fender is that the reaction force does not increase sharply under excessive load. In contrast, solid fenders’ reaction forces tend to spike sharply under excessive load conditions and damage the ship during the mooring process. This is also helped by pneumatic type fenders’ characteristic that enables a more uniform distribution of stress.

 

Advantages During Crucial Weather Conditions

 

During crucial weather conditions when the wave action is severe, mooring processes are further complicated due to up and down unbalanced action at the quay. This exerts a higher shearing force on the fenders and the frequently change in forces during mooring under such weather conditions will cause fatigue on typical solid type fenders. However on the other hand, pneumatic fender’s flexible contact area and large allowable deflection characteristics minimise fatigue during such situations. In fact, for seas with rough situations or frequent bad weather conditions, pneumatic types may be a better option than solid type fenders as it may display a longer life span.

 

Deterioration in Performance Minimised

 

Aging and fatigue often cause fenders to deteriorate in terms of performance. However, due to its air filled body and highly elastic material, such issues are minimised. Solid rubber fenders or foam fenders depend more on the hardness of the material and such dependance may result in decrease in energy absorption performance after years of usage and temperature change. On the other hand, as long as basic maintenance and air pressure control is maintained, pneumatic fenders remain optimum performance even at extremely low temperature down to -50 Degree Celsius or even during high fluctuations.

 

Tide Adaptation

Pneumatic fenders are primarily floating-types, which means the fenders float on the water in an unrestricted vertical plane corresponding to the tidal range and ship’s vertical movement. Therefore, fender energy absorption always take place at the most optimum position.

 

Features of Yokohama Fender

 

1. Guaranteed energy absorption

 

2. Chain tyre net and sling type

 

3. Thick skin construction

 

4. Good angular performance

 

5. Less surface pressure onto the side wall of ships. (The capability of accepting surface pressure of the fender is up to 14 ton/m2).

 

6. No reduction on the performance of compression when inclined.

 

7. Suitable for areas with large or small tides.

 

8. Suitable in cold weather because the compressed air as buffering medium.

 

9. Especially in mooring of large scale ships in sea docks and lightering.

 

10. Maintains large clearances between hull and structure
